Abstract
The invention provides the art with novel image sensor pixel designs comprising stacked, pinned photodiodes. The stacked pinned photodiodes provide pixels with greatly increased dynamic range. The stacked pinned photodiodes also allow improved color discrimination for low light imaging, for example utilizing pixels with no overlaying color filter array.
